GRANULES
• Biological apatites have been obtained by the
valorisation of a fishing by-product.
• Apatite granulated and isolated faceted fluorapatite
nanocrystals were obtained by a pyrolysis process.
• Optimal cell attachment and healthy proliferation
have been demonstrated by a preliminary
biocompatibility test up to 21 days.
